HEATING ELEMENT FOR WATER-HEATERS.

SPECIFICATION formingpart of Letters Patent No. 638,165, dated November 28, 1899.

Application filed October 2, 1899. Serial No. 732,351. (No model.)

To all whom it may concern:

Be it known that I, BERNHARD BECKER, a subject of the King of Prussia, German Emperor, and a resident of Godesberg, in the Province of the Rhine, German Empire, have invented a new and Improved Heating Element for W'ater-Heaters, (for which patents have been applied for in Germany on the 12th of August, 1898, and in France on the 12th of July, 1899,) of which the following is an exact specification.

My invention has relation to water-heaters, and relates particularly to the elements employed in such heaters, through which elements the water is caused to pass. Owing to the peculiar form of the heating elements allowing only small quantities of water to circulate, the water is obliged to pass a long way before it reaches the exit of an element, and a few of such elements suffice to bring the water to boiling temperature.

The accompanying drawings illustrate my improved heating element applied to a waterheater.

Figure 1 is a vertical section through line A13 of Fig. 2. Fig. 2 is a section through line 0 D of the water-heater. Fig. 3 is a detail View of a heating element in section through line E F of Fig. 2.

Each element consists of two sections suitably connected together and forming chambers a, a and a and a separating-wall e, interposed between the chambers a a and provided with apertures d. Both the chambers a and a are filled out with hollow ribs 0 of serpentine or other suitable form, so that the water circulating in these chambers is obliged to pass around all the ribs before it enters the next following element.

The course of the water through a waterheater constructed of the elements before described is as follows: The water enters through the admission-pipe b, Fig. 1, and rises through the apertures of the left and right hand sides. It first passes through the lower chamber a and follows the serpentine form of the ribs 0. Through the openings 03 it enters the upper chamber, where again the same course is followed. Arrived at the end of this upper chamber, the water rises into the pipe f and enters the second heating element, and so on until it has reached the service-pipe g.

The number of the heating elements maybe varied at will. The elements are surrounded by a casing 70, preferably of asbestos plates, so that practically all loss of heat is prevented.

The heretofore-described arrangement of heating element offers the great advantage that for repairs it can be easily taken apart. The separating-wall may also be omitted, so that the two chambers a a form one single chamber filled out with serpentine-formed ribs; but the first example offers the advantage that the water has to pass along distance, whereby the heating effect is increased enormously.

The smoke and the gases rise from the bot tom to the top of the apparatus and are obliged to pass in a zigzag line around all of the channels, wherebya thorough heating of thesame is obtained.

Having thus fully described the nature of mysaid invention, what I desire to secure by Letters Patent of the United States is A water-heating element consisting of two sections arranged one upon the other and forming the superposed chambers a, a and provided at adjacent ends with openings one above the other-one for the inlet of the water and the other for the outlet thereof, a wall 6 arranged between the sections, said wall a being provided with openings cl, and a series of hollow ribs 0 constructed and arranged within the chambers a a? in such manner relatively to each other as to divide the interior of each chamber into a sinuous water-passage, all being so arranged that the water will be caused to travel through the sinuous passage of one chamber from the point where it enters the same through the entire length of the said chamber before it enters the other chamber and is then caused to travel through the sitiuous passage of the latter chamber the entire length of same before reaching the outletopening thereof for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

BERNH. BECKER.
